Please share some more info with us, what's your operating system, have you had previous versions installed, what's your current version ofEvothings Studio? Can you please share what the Console under Tools in the Workbench states, if anything.

Are you logging in using the generated connect code, or by using your Github or Google account?

I have previously had this current version working as well as the previous versions (with Evothings Client) working.I've tried logging in using the generated connect code, as well as creating an account- with the same result.

There is no debugging output in the console.

Maybe a clue: This problem may have coincided with me building and installing a native version of my app. The native version is working, but the Viewer is now broken. I followed the instructions here: http://evothings.com/doc/build/cordova- ... ndows.html except that I was unable to install cordova@3.6.3-0.2.13 and instead installed the default which was 5.4.1. (due to some dependency issue)

I have since tried uninstalling/reinstalling the Viewer on my phone, no luck.What else should I try?Thanks,Paul

Tested with a fresh install Evothings Viewer 1.2.0 on Android 5.0.2 on LG G2, and Workbench 1.2 on OX X, it worked.

@Paul Is the custom-build app a custom version of Evothings Viewer? Or another Cordova app? A custom Viewer should install over the existing Viewer (unless the app id is changed) and should work... Installing another app build with Cordova should not have any impact. (And sorry about the outdated links in the Cordova guide, in the process of updating that.)

You can double check that the server address is https://deploy.evothings.com in the Workbench (under More/Settings) and in the Viewer (under Settings). But since you can connect I guess the server address must be ok.

Does the same error happen if you enter a new connect key and connect? There is a timeout on sessions, I think 24 hours, perhaps the session got expired.

Well, today it is just working. So I may not be able to help further. I may have restarted my phone last night, but have not restarted my computer. (yes, I know that is the first thing I should have tried...)

Anyway, to answer your questions:I built a native version of my app (which was previously running in the Evothings Viewer) using the instructions. I don't think it is a custom version of the Viewer. Anyway, it installs as it's own entry and I can run both the Viewer and my custom app.
